channel-to-channel adapter. Simulates the channel and device operations of
the channel-to-channel adapter (CTCA) connected
between two virtual machines under VM/370. Simulates the TEST I/O instruction for a virtual
channel-to-channel adapter that has no
interruptions pending.
Pageable.
Pr.ocesses the ATTACH and DETACH real devices and
channels) command.
Resident. Simulates all SIOs to a virtual console.
Pageable.
Handles the ATTACH command. Attaches a real
device to a user as a virtual device, or
dedicates all devices on a particular channel to
a specified user.
Pageable.
Chains RDEVBLOKs off the allocation chain
anchors.
Acquires virtual blocks for devices that are
likely to be attached by the ATTACH command. Scans the ATTACH and DETACH command lines and
checks syntax.
Pageable.
Handles the DETACH command.
Pageable. Verifies the existence of a device specified on
an ATTACH command.
Pageable.
Releases a virtual or real device from a virtual
user.
Pageable.
Attaches a virtual device to a user.
Defines a new virtual device for user.
Links a virtual DASD device to a user.
Pageable.
Processes error records from virtual machine via SVC 16.
Processes SVC 76 from DOS or DOS/VS. Processes SVC 76 from OS, VS/l, VS/2, or V"/370. 1-254 IBM VM/370 System Logic and Problem Deter.ination--Volume 1

associated with virtual I/O operations.
Reflects condition code 1 CSW status.
Translate a virtual I/O interruption.
Address of a table of interruption masks,
indexable by device address.
Resident.
Checks all protected shared pages associated with
shared named systems and determines if they have
been changed. If they were changed, the page is
returned to CP free storage and the condition
code is made nonzero. Switches the user's segment table entries from
one protected shared page table to the other.
Pageable. Main entry for all VMCF subfunctions. Called by DMKHVC when a DIAGNOSE X'0068' instruction is
executed. Builds a VMCBLOK with information from
user-supplied parameter list, validates the
subfunction code, and passes control to
appropriate VMCF subroutine.
Called by DMKDSP to reflect the VMCF external
interrupt message header and optional SENDX data
to a virtual machine. Copies the message header from the VMCBLOK to the user's external interrupt
buffer. If interrupt is for a SENDX request, move SENDX data to the optional area in the external
interrupt buffer.
Branched to from the DMKVKCFC entry point or
called by DMKCFP during a system reset. Releases
the master VMCBLOK and any final response VMCBLOKs (VMCRESP bit). Returns other VMCELOKs to
the original SOURCE users with the notification
that this user is not available.
Pageable.
Loaded into the user's virtual storage wben
invoked. Performs an IPL of a virtual machine. Simulates a user's IPL sequence.
Resident. Simulates the operation of privileged I/O instructions issued by virtual machines. Simulates a SIO, TIO, HIO, TCH, or CLCH. Scans a V=R channel program for exceptional
conditions, such as sense commands, no-ops, I/O to and from page 0, etc., without actually
translating the program.
Resident. Simulates all user SIOs to a virtual unit record
device (real reader, punch, print, or pseudo
timer that is spooled rather than dedicated. It
also handles control program requests to print on
the user's virtual printer. L- ____________________________________________________ CP Directories 1-255
